Java and C++

[David_Velho]

I'm an intermediate in java and c++ too. I was wondering if there is any way to exchange data between a java application and a c++ application. For eg, the java application uses the exec() method from the Runtime class (this may not be the best way to do it) to execute the c++ program . the c++ program performs some operations. 

 

(I'm not sure if I'm asking the right question)

Is there any way for the c++ program to return a specific integer to the java program to signal if the c++ application has successfully completed its task ?  I'm just curious as to how one would do it.

 

Thanks in advance.

Ps. I'm a student with exams around the corner, so i apologize if i don't reply for a while.

Pps. I used to use Blender a lot (now i don't anymore coz i don't have time and need to study), what are your thoughts on Eevee ? I heard about it yesterday and its frigging amazing! if only blender supported my amd gpu

You could have a look at the Java Native Interface (JNI).

you can run C++ code in Java.

however using exec() the c++ program can return an integer in its main function and you could use Futures in Java to handle the result.

Depending on your situation and the amount of data you want to transfer you could use mermory map files and semafors.
